I This invention relates t6 improvements in books for manifolding purposes. In practice, it has been frequently possible to eflect economies in paper and printing. costs by having some of the tickets or forms making-up a set of manifolding worksheets onl as long as is necessary and omitting space I an delineations for such entries as are not reallyneeded on such copies. This has been especially true since the appearance on the market of machines manufactured in accordance with the Shoup and Oliver Patent No. 1,396,070, by means of which it is possible to feed simultaneously forms of diiferen'tlengths "and yet have the sets of forms properly aliglned and automatically so at the end of eac feeding operation. Yet, it was heretofore supposed impossible to utilize these short and long tickets satisfactorily except in cases where the strips are not interfolded in zig-zag fashion to form a block or book.

This supposition was based on the fact that the forms of tickets are used in superposed sets that is in duplicate, triplicate or quadruplicate, etc., and since the extent of unfolding of the book in use would be controlled by the strips of the longer tickets, a surplus of the strip or strips containing the shorter tickets would accumulate and would tumble about in the register ormachine and would ultimately become balled-up and torn.

While the basis of this supposition is not erroneous, the present inventlon obviates the difliculty' above referred to by folding each strip, irres tive of the length of its tickets, in zig-zag ashion along the lines of perforations or other demarcation'sbetween adjacent tickets, and then assembling or collating the folded strips so that at one edge of the book the folds of the stripor strips having the longer tickets are nested with" the'correspondin folds of the strips having theshorter tic ets, so that the forms to be used together lie in superposed relation in sets. Consequently, the forms will be consumed in sets and W111 move from the pile or pack together irres ctive of their lengths, and no ballingup '0 the strips in the register willoccur Hence, it'will be seen that this inventlon also embraces the method of making mani folding books i which consists in separately folding the strip or strips of one lengthsheets separately from those of other length sheets to make booklets, and then collating or inter- .spersing the folds of one booklet'with the fold: of another booklet to form the book or ac r Other features, and advantages will here lnafter appear,

In the accompanying drawing- 1 Figure 1 is aperspective view of a manifolding book made in accordance with this invention.

Fig. 2 is a schematic view to show the rela tive positions of the strips of the finished book. f

Figs. 3 and 4 are perspective views of the booklets of the longer and shorter tickets respectively, before they are collated or in- ,The line of perforations 16 a so facilitates the operation of folding the strips since it weakens the strips at just the right place for the fold. Each ticket 14 may also be prop we vided with a pair of apertures' l? through the medium of which the feeding operation of the stripis controlled when the strips are used in a register su1%h as disclosed 1n the Shoup and Oliver atent No. 1,396,070, which is well known in the art.

' It is frequently desired, for the purposes of saving in the cost of the book and for other purposes,to have certain of theticketsshorter in length than others, for it is not always necessary to have all of the information contained onlcertain of the strips du licated on other strips. For instance, in the orm shown it is not necessary to have the delineated spaces 1 8,'whic h are provided on the strips Q ready for use, for if the strips 10, 11, 12 and 13 should be folded together in zig-zag fashion- 10 and 11, also appear on the strips 12 and 13,

and hence the tickets 14 of the strips 12 and 13 may be shorter in length than the tickets of the strips 10 and 11.

While this is a desideratum which realized in connection with rolled stationery where each strip is rolled on a separate core, it has been heretofore unobtainable in a zigzag folded pack or book .of worksheets to have the strips-folded in superposed relation at predetermined distances governed by the form lengths of the longer tickets 14 of the strips 10 and 11, it would be necessary for the longer'tickets to pull themselves from between a stack of shorter tickets, as the consumption of the pack continues, with the 1 result that the stack of shorter tickets would tumble about in the register and become balled-up and ultimately torn.

The desideratum above referred to has, however, been obtained by the present invention by'folding the strips having the same form lengths which are the strips 10 and 11 in the form s own, separately and independently of the operation of folding the strip or strips having the shorter form lengths,

12 and 13 in the form shown. Accordingly, the strips 10 and 11, the tickets of which are of the same lengths, are placed in super osed and registering relation and then are olded along the lines of perforations 14 in the usual manner, that is tosa by, hand, so thata' booklet 19 is produce Then the strips 12 and 13, which are made up of the shorter produce the booklet 20.

tickets, are likewise superposed and folded to Finally, to produce the pack, it is merely necessary to interleave or collate the superposed folded sheets of the booklet 19 with those of booklet 20,

so that the folds 21 of the strips 12 and 13 embrace and lie upon the folds 22 of the strips 10 and 11, the folds 23 and'the stfi ps 12 and 13 bein located inside but substan tially removed rom the folds 24 on the strips 10 and 11. This is clearly shown in Fig. 2, in which the heavy lines indicate the strips 10 and 11 while the lighter lines indicate the strips 12 and 13. v v

With the worksheets so folded at each feed- 7 ing operation of the machine, one layer of forms or ticketwill be taken from the pile and no surplus length of any strip is allowed to remain in the machine and become bal1edup with the other strips.- 4 A 'The manifolding book of this invention may also be produced by the folding machine disclosed in my copending application Serial 7 No. 512,7 61, filed February 2, 1931, in which the folding machines disclosed in my patent, No. 1,805,161, granted April 12, 1931, and in my application Serial No. 392,540, filed September 14, 1929, have been improved and modified to provide a feed mechanism for has been i feeding the strips form-lengths regardless of the lengths of the forms, so that in the folding operation the folds-of the several strips extending in one direction will be nested worksheet strips, each strip having a succession of sheets with folds in opposite directions along the lines where the sheets adjoin, the distance between the folds of one strip being greater than the distance between the folds on another of the strips, and the folds inone direction of one of the strips being nested with the folds in like direction of another of the strips. 7
